To all whom it may concern:

Be it known that 1, ARTHUR HOPKINS BEARD, a citizen of the UnitedStates, and a resident of Memphis, in the county of Shelby and State ofTennessee, have invented a new and Improved Electroma etic Motors, ofwhich the following is a fu clean-and exact description. My inventionrelates to a motor in which the application of magnetic force induced byelectricity is applied in a most economical and efficient manner.

' The principal objects of the invention are to transform the energy dueto electricity and magnetism into 0t and apply it to useful purposeseconomical and efficient manner.

. Reference is to be had to. the accompanying drawing forming a part ofthis specification, in which the figure is a side elevation of amotorillustrating the principle of my invention. a I Y I provide a motiveower by connecting a source of power, as a electric circuit b and a olechanger c of ordiconstruction, with a conductor b, which'is adapted toenergize two magnets d. It will be observed that if the pole changer isprovided with means for operating it the circuit formed by theconductors b and b will alternately and simultaneously magnetite themagnets (Z in opposite directions. These magnetsare provided with polesd, and vibrating between these poles in the field of force '1 locate apermanent or electro-magnet c. This magnet is preferably doubleand ismounted upon a lever f which'is pivoted on the frame of the machine. 7This lever is pro vided at the end of its opposite arm with a linkoperating a crank it which turns a shaft k. %n this shaft is mounted afl wheel Z pulley m. The s aft may with a crank o anda link foroperating the polechanger, but the'po e changer can be operated directlyfrom the shaft by the use of a commutator. The magnet e is energized bya source of power represented by a battery 0 and conductors b", thedirection of the current and of the ma netic flux being constant. p

he operation of the device will be readily understood The currents(either chemical or frictional) being turned on, the current around themagnets d will be reyersed and returned to the original direction onceduring each revolution of in a most and, if desired, a

magnets e is in a constant direction, the tracted and repelle by eitherof the poles of the electro-rnagnets d, the actions on the two magnets ebeing simultaneous but opposite. The lever f vibrates and this motionthen keeps the shaft lr in operation, the fly wheel operating in comedead centers and equalize the force.

Power may be takenfrom the shaft b conare each alternately attheordinary manner to overnecting the pulley m with other mac inery or inany ordinary manner.

The two electro-magnets d are of the horse shoe type and r and lowermagnets d are on a radial hne the two poles of the upom the center ofoscillation of the lever f, and in like manner the poles of the magnetse e are on a radial line from'such center. a It therefore results thatthe generalposition of all the magnets conforms to a circular curve,giving the magnets-anoblique arrangement.

he poles of the stationary and movable magnets are also of interlockingor telescopic to each other, 'i. a, thestationary magnets d have reducedpole ends d that enter corresponding slots or sockets in, the pole endsofthe movable magnets. IThis, while ly considered, has

nevertheless a s ecial correlation and coordinated value w en apivoted'leverg carrying the movable magnets oscillates etween twostationary magnets reversely charged, which I will now proceed to exlai'n. I In the position shown in the rawing there are two forcestendingto bring down the left hand end of lever f. One force is therepel lent action which the upper stationary magnet (i exerts upon theupper movable magnet e and .the other'force is the attractive forcewhich the (oppositely charged) lower stationary magnet" d exerts u ablemagnet e. The or er in which these forces act, is as follows. Thedownward movement gets its initial power from the repellent action ofthe nppermagnets, and as;

Then when on the lower mov- I tion, aside from its magnetic value, inthat when such magnets, acting by both repulsion and attraction, aremounted on a pivoted lever, as in my invention, the initial re ellentforce is very great and but for the reel rocal fit and guiding effect ofthe interlocke poles in receding, the movable magnets in this thrust orrepellent movement would have a tendency to twist sidewise on the leverand lose their coaxial position. This is'a result of great importance inthe repellant movement, since the power is a thrust which would causethe magnets to separate with a sidewise twist and leave the coaxialrelation,

- while in the attraction movement the tendency is to seek the coaxialrelation by mutual aiiinity.

Having thus described my' invention, I claim:

1. An electro-magnetic motor, comprising a pivoted lever bearing ononeend two electro-magncts with oppositely projecting poles arranged onlines radial to the center of the lever and continuously wound helices,a sinle electric circuit normal] closed through hoth said helices, twostationary electromagnets arranged on opposite sides of the movablemagnets with oles facing those of the intermediate movable magnets andarranged on the radial lines of the levers center, an electric circuitpassing through the coils of both stationary magnets, a pole changer foralternately reversing-this circuit, and mechanical means for shiftingthe pole changer by the oscillation of the lever.
